FUME-ARRESTER FOR CHIMNEY-FLUES.

SPECIFICATION forming part of Letters Application tiled May 29, 1882.

To all whom it may concern:

Be it knownthat l, MAX FEEUDENBERG, of Ems, a subject ot' the' Emperor of Germany, and residing at Ems, Germany, have invented new and useful Improvements in Fume-Arresters for Chimney-Fines, of which the following is a specification.

The object of my invention is to facilitate the depositing' of particles ot' metal in the lues ot metallurgical Works, through which liues the smoke or fumes containing the particles of metal to be deposited pass.

Reference is to be had to the accompanying drawings, which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a cross-sectional elevation of my improved iue. Fig'. 2 is a sectional plan view of the same.

The amount of metallic particles or dustdeposited on the walls or tiue through which smoke or fumes containing these particles are conducted depends upon the superficial area of the walls or sides of the liuc, and in order to get a large deposit the superficial area of the walls of the flue must beincreased as much as possible. To accomplish this I arrange thin sheets B, of metal, wire-netting, or fabric, in the line A or in the smoke-chamber parallel with the direction ot' the draft. These plates or longitudinal partitions are impended from the root ofthe flue by means of hooks D or any othersu'itable devices. The longitudinal plates or partitions d o not extend down to the floor of the ue, but only to the upper edges of transverse partitions C, which are about two forming part of this specilication, iuY

(No model.) Patented in Germany August 26, 1881, No.17,513 in England October 20, 18H1, No. 4,590, and in Austria-Hungary March 12, 1882,

No. 3,723 and No. 8,454.

| feet high and are located about teu feet apart. The longitudinal plates or partitions B must be as thin as possible, so as to occupy very little space, and so as not to interfere with the draft. The metallic particles or dust contained in the fumes or smoke carried through the flue by the draft aredeposited on the plates or partitions B. The partitions C form compartments into which the surplus of the metallic particles deposited on the plates B drop to prevent them from being carried oft'by the draft or current of air. I have shown six plates lwn the flue; but the number may be increased or decreased as the circumstances may require.

I am aware that shelfpartitions have been Y employed to extend alternately from opposite sides of the Hue, but not quite across, for the purpose of retarding the current of the products of combustion; also, that bags of textile fabric have been used for a somewhat analogous purpose; but

The combination, with the furnace-Hue A, of the transverse partitions C,arran ged above the bottom, and the parallelplates B, the latter extending lengthwise of the flue from the Vtop to the partition, as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
